Jam in my leg

My second Fasciotomy operation in the early 1990s to relieve the pressure from chronic compartment stress syndrome under my shins from playing touch football - but the op had a slight complication...

It was a haematoma from internal bleeding after the operation, which revealed an open wound when the stitches were to come out a few weeks after the operation. The blood was collagulated like blackberry jam and was squeezed out quite easily by the surgeon.
